摘要
颗粒物浓度测量是计量测试技术中的一个重要方面 ,但迄今为止 ,国内外尚缺少这方面的标准物质。文中提出了一种简单可靠而又十分实用的“定量稀释法” ,能很好地解决这一困难。
The Standard Reference Materials (SRM) for the purpose of particulate concentration verification are now very rare in the world market. In this paper a simple and reliable method, called “metered dilution method”, is presented which has been proven by the experimental studies to be useful and can be used in the concentration verification.
